a Bible passage
31It is a fearful thing to fall into the hands of the living God.
31. fearful … to fall into the hands—It is good like David to fall into the hands of God, rather than man, when one does so with filial faith in his father's love, though God chastises him. "It is fearful" to fall into His hands as a reprobate and presumptuous sinner doomed to His just vengeance as Judge (Heb 10:27).
living God—therefore able to punish for ever (Mt 10:28).
